Beginning on May 1st 2012, the Portuguese extension .PT will be available to those outside Portugal.

You will still need to provide an ID number, but it will no longer be limited to Portuguese citizens. The first major change is that there is no longer any need to have a personal or company name that is the same as the domain!

For example:

If you are a registered organization (company, association, etc.) in Europe (EEC), you must provide your Intra-Community VAT number. If you are not in Europe, you must provide a different fiscal ID number.

If you are an individual who is a citizen of Portugal, you must provide your Fiscal Code. If you are not Portuguese, you must provide your passport number.
